Olive waste briquetting information (part #2)

Olive waste briquetting information (part #2)

Question : 

How much olive stones would you need ideally? I also have this other question:

Is it possible to make briquettes or logs like yours WITHOUT any binder. I am talking in general here (not especially about the olive stones).

I am asking this question because I met a potential “competitor” that bought material (from Italy) that will allow him to compact olive stones into briquettes. This competitor does not plan to char the stones but just compact the stones into briquettes and sell them.

according to him, his briquettes will be made without binder. is it possible or he wanted just to impress me?


Answer : 

Let us refer to charred briquette as “Charcoal Briquette” and not charred briquette as “Biomass briquette” in order not to be confused. What we offered to you is charcoal briquette making machine to make briquette from charcoal or charred material. Charcoal briquette market is virtually different from biomass briquette market.

Charcoal briquette is for BBQ, grill restaurants, hotel, home-use, food industry and else. So, the price is completely better than the biomass briquette which is to be used as fuel (giving heat, sell as calorific value).

If you plan to make biomass briquette (briquette from olive stone), the process is called hot press process using heat to bind the biomass. You can carbonize this briquette later to get the charcoal if you want (need kiln for carbonization, same as making wood charcoal from wood log). The offered machine is the smallest size because this process requires much higher horse power machine.

I do not think there will be any problem with machine for charcoal briquette production.

Regarding briquette making from olive stone, we do not have the test machine now but we have experiences with what is called “olive husk” and dry olive waste. It can be made into briquette without problem (actually it smelled very good when making briquette). However, I want just to make sure if your sample is what we imagine or not. So, only little of sample to see would be enough.

I hope you are not getting tired of the questions but I still have these:

You wrote that (I quote) : “.. Anyway, higher the density of the briquette is, the longer the drying time requires..”.

the more compacted the briquettes are, the more time it requires to dry?
It is correct?
[Answer]: Yes,  you understand correctly.
second question: If I succeed to get decent briquettes manually (which means without using a presses), can I assume that the result will be even better when I will be using a hydraulic press?
[Answer]: Yes, it is supposed to be that way. The result may be a lot better that making briquette by hand because you will never reach such high pressure the machine can do.

last question : are you building your own machines that you are selling?
[Answer]: Yes, we build our own machines everything by ourselves. The reason I suggested you try to find the standard hydraulic press unit (as photo) is that it would be easy and much cheaper for you.


Actually, the latest try gave me the impression that it might be a good idea to grind first the olive stones, char the grinded stones and then mold them. When molded, then they can be charred.

That is the latest idea I came with but I have not applied it yet to see if it is a better option. i thought of that because I noticed that the smaller the olive stones were, the quickest the charring process was. therefore, if I were to grind to stones into a powder, the charring process will be faster.

All my test so far were following this succession of steps : char the olive stones, grind them and then mold them.

I might stick to this process for the moment.

I will have plenty of olive stones available for my tests (I can even send some to you).

I can find different machines to char and grind, As for the molding machine, I am not sure there are any over there (i have not found any so far). That is why i though of you.

Out of curiosity : do you think, it is possible to make briquettes without adding any binder?

Answer : 

It would be great if you can send the sample to us to make the briquette for your reference.

It cannot be made into briquette without binder. Please note that the binding agent can be anything that gives stickiness, i.e.starch, flour, molasses, etc.

It is need to confirm the raw material first to offer the right equipment set to you. The charcoal briquette making from charcoal chunk/powder is the common method and proven technology. More than half of the charcoal briquette being sold in the market is this type. So, it would be great if you can char your raw material first. You can also mix them with other charcoal or some other fine materials too to improve the quality or reduce the cost.

Fine Coal (Petroleum Coke) pellet making test using small pellet machine 7.5 HP

Fine Petroleum Coke – Pellet making test by small machine (7.5 HP)
The sample is very dry. Using small machine could not press successfully. It requires water or binder to help improve pellet forming and strength.
If using higher power motor, this would help improve the forming and process-ability.
